Older and cheapest computers may have some performance issues during video meetings, especially when using highest picture quality. New driver software from manufacturer’s web pages may help, but often the best way to get full performance out of a computer is to turn possible power saving functions temporarily off (they tend to slow especially laptop computers down). It is also recommended to avoid running heavy applications simultaneously with a video meeting.
